Meridian’s Annual Report evidence of solid financial performance For immediate release: 14 October 2011 Meridian Energy Limited’s Annual Report for the year ended 30 June 2011, which was tabled in Parliament today, provides more evidence of the successful delivery of the company’s strategy. As previously reported Meridian has achieved a solid financial performance for the 2010/11 year against a backdrop of challenging conditions. During the year, we have seen relatively flat electricity demand, the Christchurch earthquakes, warm autumn/early winter conditions, high hydro storage levels and an intensely competitive retail market. Chief Executive Tim Lusk says Meridian’s ability to deliver solid EBITDAF growth in these conditions reflects the success of the company’s strategy. “Our focus has been on operating a strong, integrated business, optimising our portfolio of assets, paying close attention to cost, and improving returns from our international operations. “We’ve also made significant progress in our retail performance in a highly competitive market with meaningful improvements in customer numbers and satisfaction levels,” says Mr Lusk. The successful commissioning of Te Uku wind farm, commencement of construction on the Macarthur wind farm and the growth of our generation option portfolio support future value growth through our renewable development focus. Meridian’s commitment to strong shareholder returns is highlighted by a special dividend of $684.6million paid during the year and maintenance of a BBB+ (stable outlook) credit rating with Standard and Poor’s. Meridian is well positioned for future growth. Meridian’s medium-term development pipeline has options well placed in the generation merit order to meet future demand growth expectations. As a utility scale generator, Meridian will benefit as wholesale prices are expected to increase, trending towards the marginal cost of generation over the longer term. New arrangements with our largest customer, Rio Tinto Alcan New Zealand Limited, provide improved commercial certainty from 2013. Alleviation of transmission grid constraints, through investment such as the HVDC upgrade, will improve Meridian’s portfolio flexibility and risk position.
